If you are considering a new Ultra HD 4K monitor then it is likely you will need a new system update to drive those 8,294,400 pixels. Right now the cost of 4k capable graphics cards is prohibitive for all but the wealthiest of gamers. When we reviewed the Titan X last month we noticed performance could still drop under 60 frames per second when dealing with the most demanding engines. We slot another card into our test bed – we answer the question ‘Are two Titan X's enough to drive 60fps+ at 4K?'

The Nvidia Titan X is based around the physically large GM200 die and is built on the 28nm process.

This is an extended 28nm die, 50 percent bigger than the one found on the GTX980. There are two more GPC clusters, enhancing the specifications to 3,072 cores and 192 texture units.

The Nvidia Titan X has 32 more ROPS than the GTX980, totaling 96. The memory interface has been set at a broad 384 bit … comprised of 6 x 64 bit pathways. This is more in line with the older generation of Nvidia hardware, like the GTX780 Ti – as the newer hardware has depended extensively on colour compression algorithms to improve overall efficiency.

Many readers are still under the impression that the Titan range of cards are not designed for gamers, but as I have explained multiple times, Nvidia have been marketing Titan hardware to the gaming enthusiast for years. Don’t take my word for it – the Titan Z for instance, according to Nvidia is a ‘gaming monster’. The Titan Black ‘gives you the added horsepower to drive your most graphics-intensive games’ – all on the Nvidia website here.

According to industry insiders, over 85% of all Titan sales are to the gaming enthusiast.

It is true that many professionals may have considered a Titan oriented graphics card, due to the double precision support. The standard Titan can handle DP calculations at 1/4 SP speed – which when compared directly to the 1/24 rate of the GTX780 Ti, is incredibly quick. The GTX 980 is rated at 1/32 SP and the Titan X is unfortunately no quicker. If you need a graphics card for double precision processing capabilities, then the Titan X is not for you – it is actually slower than the Kepler based Titan hardware from the previous generation.

Nvidia obviously want you to pay more for Double Precision performance, and they (not surprisingly) have a range of wallet sapping Quadro cards on offer, designed to deliver the goods. An example is the Quadro M6000 – built on the same GM200 die as the Titan X, but with much better DP performance. Just be prepared to pay out the ying-yang for the pleasure.
